Dynamics and entanglement of photon pulses in a photonic crystal — •Carsten Henkel and Geesche Boedecker — Institut für Physik, Universität Potsdam

In a photonic crystal, the dispersion relation of light can be tailored to a great extent. Close to a band edge, for example, the group velocity is significantly reduced. For a finite crystal slab, multiple reflections from the end faces lead to a transmitted pulse train. We discuss the entanglement properties of the transmitted pulses. The pulse shape inside the crystal is analyzed for a one-dimensional model [1] in the regime of small group velocities.
